[0002] The principle of a heater is energy conversion, most commonly the conversion of electrical energy into heat energy. A gas heater is an electric heater used to heat gas. It has a gas channel inside the heater. When the gas flows through the gas channel, it is heated by the heating wire. However, existing devices have certain problems in use and still need to be continuously improved.

[0003] A search revealed that patent publication number CN218993675U discloses an integrated gas heater, comprising a device body with bases fixedly connected to both sides of its lower surface. Each base has several threaded holes on its lower surface, allowing it to be fixedly connected to the ground or a mounting plate via these holes and bolts. The heater also includes: an air inlet mechanism, one end of which is fixedly connected to one side of the device body and located inside the device body; an operator, fixedly connected to one side of the front of the device body; and an air outlet mechanism, one end of which is fixedly connected to the other side of the device body. Through the included heating mechanism, the device effectively achieves gas diversion for heating, accelerating the heating process and saving heating time, energy, and production costs. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] In order to dissipate heat from the main controller and wireless module installed in the heat insulation chamber, the device has heat dissipation holes on the top of the device body. However, there is no protective structure at the heat dissipation holes, which makes it easy for dust in the outside air to enter the heat insulation chamber and adhere to the main controller and wireless module, thereby affecting the heat dissipation effect of the main controller and wireless module.

[0005] Therefore, an online gas heating device with adaptive adjustment function is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an online gas heating device with adaptive adjustment function to solve the problems mentioned in the background art.

[0008] Preferably, a heat insulation chamber is welded to the top of the outer casing and directly below the heat dissipation vent. A temperature sensor is installed inside the heat insulation chamber, and a wireless module is installed inside the heat insulation chamber and next to the temperature sensor. The temperature sensor is electrically connected to the wireless module.

[0009] Preferably, a heating chamber is provided inside the outer shell, an air pump is installed at one end of the heating chamber, an air inlet pipe is connected to the input end of the air pump, and one end of the air inlet pipe is fixedly inserted through the side wall of the outer shell.

[0010] Preferably, the air pump output end is connected to an output pipe, and four spiral tubes are connected to the output pipe.

[0011] Preferably, each of the four spiral tubes has an exhaust pipe fixedly connected to its other end, and one end of each of the four exhaust pipes passes through the heating chamber and the side wall of the outer shell in sequence.

[0012] Preferably, a set of heating tubes is installed at both the upper and lower positions inside the heating cavity, and a temperature regulator electrically connected to the four spiral tubes is installed on the outer side of one end of the heating cavity.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with existing technologies, by adding a connecting frame and a filter screen, the filter screen can filter dust in the gas entering the heat insulation chamber, preventing dust from entering the heat insulation chamber and adhering to the temperature sensor and wireless module, thus affecting their heat dissipation. At the same time, by squeezing the stop block through the compression spring, the stop block drives the limit rod to move towards the limit hole opened on the side wall of the connecting frame, thereby enabling quick and convenient installation or removal of the connecting frame and the filter screen. This facilitates the inspection and maintenance of the temperature sensor and wireless module in the heat insulation chamber, and also allows for the cleaning of dust from the surface of the removed filter screen, improving the practicality of the device.

[0021] Example 1

[0022] As attached Figures 1 to 4 The online gas heating device with adaptive adjustment function shown includes an outer shell 1. A heat dissipation port 2 is opened at the top of the outer shell 1. A connecting frame 3 is set inside the heat dissipation port 2. A filter screen 4 is fixedly connected to the connecting frame 3. Two connecting blocks 5 are symmetrically welded on the front and rear sides of the connecting frame 3. A limiting hole 12 is opened on the left and right sides of the connecting frame 3. Two mounting cavities 6 are symmetrically opened at the top of the outer shell 1. A limiting rod 7 is movably set in each of the two mounting cavities 6. A stop block 8 is fixedly connected to the outside of the limiting rod 7. A compression spring 9 is sleeved on the outside of the limiting rod 7. A toggle rod 10 is fixedly connected to the outside of one end of the limiting rod 7. Two L-shaped sliding grooves 11 are symmetrically opened at the top of the outer shell 1 and communicate with the mounting cavities 6. The two toggle rods 10 are slidably connected in the L-shaped sliding grooves 11.

[0023] In use, the device can first pull the limiting rod 7 by using the lever 10, so that one end of the limiting rod 7 is away from the heat dissipation vent 2 at the top of the outer shell 1. At the same time, the lever 10 is pulled and slides in the L-shaped slide groove 11. Finally, the lever 10 is rotated to lock the lever 10 at the end of the L-shaped slide groove 11. Then, the connecting frame 3 and the filter screen 4 are placed in the heat dissipation vent 2 at the top of the outer shell 1, and the bottom wall of the connecting block 5 is in contact with the top surface of the outer shell 1. Then, the lever 10 is rotated to release the locking of the lever 10 by the L-shaped slide groove 11. Then, the lever 10 is released. At this time, the compression spring 9 compresses the stop block 8, and the stop block 8 drives the limiting rod 7 to move closer to the limiting hole 12 on the side wall of the connecting frame 3. This allows for quick and convenient installation or removal of the connecting frame 3 and the filter screen 4. It also facilitates the inspection and maintenance of the temperature sensor 14 and the wireless module 15 in the heat insulation chamber 13, and allows for the cleaning of dust on the surface of the removed filter screen 4, improving the practicality of the device.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, a heat insulation chamber 13 is welded to the top of the outer casing 1 and directly below the heat dissipation vent 2. A temperature sensor 14 is installed inside the heat insulation chamber 13. The temperature sensor 14 includes a detection probe (not shown) that senses the temperature of the heated air. This detection probe is installed inside the spiral tube 20 and is electrically connected to the main body of the temperature sensor 14. The main body of the temperature sensor 14 senses the heating temperature of the air inside the spiral tube 20 through the detection probe, and then converts and transmits the detected temperature signal. Simultaneously, a wireless module 15 is installed inside the heat insulation chamber 13 and next to the temperature sensor 14. The temperature sensor 14 is electrically connected to the wireless module 15. The wireless module 15 receives and transmits the temperature information detected by the temperature sensor 14 and is electrically connected to an external terminal. The wireless module 15 provides a wireless remote monitoring and operation mode for this device, allowing users to remotely understand and adjust the temperature of the heated air.

[0027] In a preferred embodiment, a heating chamber 16 is provided inside the outer shell 1. An air pump 21 is installed at one end of the heating chamber 16. An air inlet pipe 18 is connected to the input end of the air pump 21. One end of the air inlet pipe 18 is fixedly passed through the side wall of the outer shell 1. An output pipe is connected to the output end of the air pump 21. Four spiral tubes 20 are connected to the output pipe. An exhaust pipe 19 is fixedly connected to the other end of each of the four spiral tubes 20. One end of each of the four exhaust pipes 19 passes through the heating chamber 16 and the side wall of the outer shell 1 in sequence. A set of heating tubes 1 is installed at both the upper and lower positions inside the heating chamber 16. 7. A temperature regulator electrically connected to four spiral tubes 20 is installed on the outer side of one end of the heating chamber 16. Furthermore, when the device is in use, the air pump 21 transmits the gas to be heated to the spiral tubes 20 through the air inlet pipe 18. At the same time, the power supply to the heating tube 17 in the heating chamber 16 is turned on, and the gas in the spiral tubes 20 is heated through the heating tube 17. After heating is completed, the gas is discharged through the exhaust pipe 19. At the same time, the temperature regulator electrically connected to the heating tube 17 can adjust and control the temperature of the heating tube 17, so that the heating tube 17 can regulate the heating temperature in the spiral tubes 20.

[0028] The working process of this utility model is as follows: First, the air pump 21 transmits the gas to be heated to the spiral tube 20 through the air inlet pipe 18. At the same time, the power supply of the heating tube 17 in the heating chamber 16 is turned on, and the gas in the spiral tube 20 is heated through the heating tube 17. After heating is completed, the gas is discharged through the exhaust pipe 19. At the same time, the main component of the temperature sensor 14 senses the heating temperature of the air in the spiral tube 20 through the detection probe. Then, the main component of the temperature sensor 14 converts and transmits the detected temperature signal. Then, the wireless module 15 receives and transmits the temperature information detected by the temperature sensor 14. The wireless module 15 is electrically connected to an external terminal. The wireless module 15 provides a wireless remote monitoring and operation mode for this device, which makes it convenient for users to remotely understand the temperature of the heated air of the device. The wireless module 15 controls the temperature regulator, and the regulator is electrically connected to the heating tube 17 to adjust and control the temperature of the heating tube 17.

[0029] When the filter 4 needs to be installed and used, firstly, the limiting rod 7 can be pulled by the lever 10, so that one end of the limiting rod 7 is away from the heat dissipation vent 2 at the top of the outer shell 1. At the same time, the lever 10, which is pulled, slides in the L-shaped slide groove 11. Finally, the lever 10 is rotated to lock the lever 10 into the end of the L-shaped slide groove 11. Then, the connecting frame 3 and the filter 4 are placed in the heat dissipation vent 2 at the top of the outer shell 1, and the bottom wall of the connecting block 5 is in contact with the top surface of the outer shell 1. Then, the lever 10 is rotated to release the L-shaped slide groove 11. The lever 10 is engaged and then released. At this time, the compression spring 9 compresses the stop block 8, which in turn drives the limit rod 7 to approach the limit hole 12 opened on the side wall of the connecting frame 3. This allows for quick and convenient installation or removal of the connecting frame 3 and the filter screen 4. It also facilitates the inspection and maintenance of the temperature sensor 14 and the wireless module 15 inside the heat insulation chamber 13, and allows for the cleaning of dust from the surface of the removed filter screen 4. The above describes the working principle of this online gas heating device with adaptive adjustment function.
